Well, I've had my 328i for just over 2 months and drove about 2100 miles. My ave mpg went from 14.7mpg to 15.1 mpg. Most of it is city driving or bumper-to-bumper stop-and-go traffic on LA Freeway. Nowhere near 20. If I somehow can get it to 16-17mpg I'd be extatic

Absolutic, make sure your tire pressure is set correctly and check it every 2 weeks. My 330xi is heavier than your car and I average 22 mpg (tank-to-tank) with 75% highway, no stop and go.

My 328i 6MT is about 1 month old. The on-board computer shows an average of 20 mpg for the 800 miles so far. I drive 80% city, 20% hwy. Occasionally I would sprint from stop lights, but never sit in traffic. When cruising at 65, the MPG gauge shows over 30 mpg. So, basically, my experience is on par with the EPA number that BMW claims. I am very happy with it and hope the number will get even better after the break in period (400 more miles to go).
 
Absolutic, check the MPG gauge when you cruise on the highway -- maybe at night or on weekend. If it reads 30 or better, your car is just fine and traffic is to blame.

My 2007 328 has 890 mi so far. 15mpg city, 20.1 highway. Very disappointing. My 2003 325 always got over 20 city and 28-30 highway. Can the 3 liter engine make that much differenc? no way.

jtla, my MPG gauge also show over 30 mpg on a freeway. It is just that I am rarely on freeway, I am in LA stop-and-go traffic to work and from work, daily grind, 15 miles to work, 15 miles back, that 15 miles take me 35-50 minutes on average. Or I can be parked on 405 freeway - I don't think that is going to improve my mileage. I am firmly at 15mpg. I do check my tire pressure - it is proper. I never believe the EPA figures. EPA figures are derived from all 1970s EPA tests where they put cars on treadmills in some hall, and then report the mileage to us. On my Jeep Grand Cherokee before I averaged 12.3 mpg, On my Mercedes ML350 I averaged 13 mpg, so 15mpg om my 2007 BMW 328i is quite an improvement (in my eyes).

Which model is that?
 
So far the posts here where 325i/328i/330i with mpg 20 to 30 average depending on city or highway use.
 
I am currently pondering replacing my old battered 1997 Geo Prism with a nice 3-series BMW, but I am so used to getting 30mpg out of driving 15% city 85% highway without having to limit my desire for speed in any way (read: above 80 where traffic permits) that I wonder how much worse it would be with the stronger, newer and more expensive car... I don't want to be stuck behind hybrids just to be fuel efficient

I have a 328 coupe. Disappointingly it gives me 20 mpg irrespective the TLC with which I drive it. Highway driving vs city driving hardly ever seems to make a difference. I hardly ever drive during the rush hours so most of my driving is on open roads and I still end up with such a low figure. Anybody else with a 328 coupe who is getting similar figures?
 
Is this expected or should I take it in for an inspection?

That sounds low. I'm assuming you have an automatic. Do you drive in sport mode? Are you measuring the gas mileage by the computer or gallons filled at the gas station? Maybe an ecu flash is needed? Is it fully broken in? Take it into BMW and see what they say.

I am assuming tire pressure is checked every 3 weeks and premium gasoline is your choice.
